The device can generally provide linear and/or angular degrees of freedom for positioning of the medical instrument prior to an insertion of the medical instrument. The medical insertion device includes a mounting arm, an interface connected to the mounting arm for interfacing with a medical instrument, a mechanism for movement of the medical instrument or a part of the medical instrument in an insertion direction, a carriage connected to a distal end of the mounting arm, and a pivot connection between the carriage and the distal end of the mounting arm to permit pitch or yaw of the mounting arm.

CROSS-REFERENCE

This application is a continuation of U.S. patent application Ser. No.13/512,198, which claims the benefit of U.S. Provisional PatentApplication No. 61/264,761 filed Nov. 27, 2009 and U.S. ProvisionalPatent Application No. 61/334,851 filed May 14, 2010, the disclosures ofall the foregoing of which are incorporated by reference herein in theirentirety as if fully set forth herein.

FIELD

Some example embodiments described herein relate to surgical robotics,and in particular to control of medical instruments which have aninsertion action, such as a biopsy needle or ablation tool.

BACKGROUND

Cancer diagnosis and treatment can require the medical practitioner tobe able to pin point a suspicious lesion within the patient. After thearea is located, the next step in a typical treatment process caninclude a biopsy procedure to identify the pathology, which can beperformed in the operating room, with the patient under generalanesthetic. In other instances, biopsy procedures can include theimplementation of core needle biopsy procedures using minimally invasivecore needle extraction methods.

Difficulties can arise in performing of a conventional procedure. As anexample, for breast biopsy with magnetic resonance imaging (MRI)systems, the patient may have to be shuttled in and out of the magnetseveral times before a biopsy is actually performed. During this time,the contrast agent could have already lost some of its effect and imagequality could suffer. This process itself may be time consuming andcumbersome, especially in a time-sensitive environment.

In addition, contrast laden blood from a hematoma as well as an airpocket at the biopsy site can make it difficult to subsequently verifythat the correct site identified from the imaging system was biopsied,or to rapidly confirm that the sample obtained has a suspect morphology.This practice could also require removal of a relatively large volume oftissue, with a fraction of that assumed to be from the lesion.

SUMMARY

It would be advantageous to provide a medical insertion device which maybe used within an imaging system in real-time or near real-time.

Example embodiments relate to a method for detecting, diagnosing, andtreating an area of interest in a patient, said method comprising thesteps of (i) placing a patient in a position for retrieving medicalinformation from the patient; (ii) retrieving the medical informationfrom the patient while in the position; (iii) analyzing the medicalinformation to determine an area of interest; (iv) while maintaining theposition of the patient, assessing the area of interest to determine amedical intervention for the area; and (v) while maintaining theposition of the patient, performing the medical intervention on thepatient in the area of interest.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Cancer diagnosis or procedures can include using a biopsy tool toretrieve a tissue sample for further analysis. A difficulty with someexisting medical systems is that the health practitioner may not be ableto work within a CT or MRI system during scanning for procedures such asbiopsy or ablation therapy.

Many imaging systems may also have limited space constraints forplacement of robotic systems.

Some example embodiments relate to an image guided, automated surgicalrobotic system having a manipulator, and associated workstations for thepurpose of obtaining a biopsy sample and/or treating an identifiedlesion/pathology. The system can interface with existing clinicaldiagnostic imaging systems such as magnetic resonance imaging (MRI) tohelp chose a specific target and then automatically orsemi-automatically drive a medical instrument such as a percutaneouscoring needle biopsy device or ablation tool, under real-time ornear-real-time image guidance.

In an example embodiment, there is provided a robotic system, includingan insertion device having an interface for interfacing with a medicalinstrument, one or more mechanisms for effecting insertion of themedical instrument or a part of the medical instrument in an insertiondirection, and for effecting pitch and yaw of the insertion device, adetector subsystem for determining spatial information, and a controllerin communication with the detector subsystem and configured toautomatically control the one or more mechanisms based on the receivedspatial information.

In another example embodiment, there is provided a medical insertiondevice which includes a mounting arm, an interface connected to themounting arm for interfacing with a medical instrument, a mechanism formovement of the medical instrument or a part of the medical instrumentin an insertion direction, a carriage connected to a distal end of themounting arm, and a pivot connection between the carriage and the distalend of the mounting arm to permit pitch or yaw of the mounting arm.

In another example embodiment, there is provided a method forfacilitating insertion of a medical instrument, or the use of themedical instrument, which includes: interfacing the medical instrumentwith an interface, the interface being connected to a mounting arm,pivoting the mounting arm at a pivot connection connected between acarriage and a distal end of the mounting arm to effect pitch or yaw ofthe mounting arm, and moving the medical instrument or a part of themedical instrument in an insertion direction.

In another example embodiment, there is provided a dispenser system foruse with an imaging system, which includes a dispenser frame adjoined tothe imaging system, the dispenser frame including or defining at leastone instrument holder for holding and releasably providing of a medicalinstrument.

Reference is first made to FIGS. 1A and 1B, which show a medicalinsertion device 100 in accordance with an example embodiment.Generally, the medical insertion device 100 may be used with orinstalled within an imaging system (not shown here), such as a magneticresonance imaging (MRI) system, during scanning. The medical insertiondevice 100 can generally be used to retain, position and effectinsertion of a medical instrument 102, for example a biopsy device 103as shown, or for example a treatment device. The device 100 cangenerally provide linear, angular and/or rotational degrees of freedomfor positioning of the medical instrument 102 prior to insertion of themedical instrument 102.

As shown in FIG. 1B, the medical insertion device 100 includes a frame104 which acts to house the medical insertion device 100. The medicalinsertion device 100 further includes a linear slide assembly 106mounted or connected to the frame 104. The medical insertion devicefurther includes a rotary drive assembly 108 for generally driving thelinear slide assembly 106, and a carriage assembly 110 for moving alongthe linear slide assembly 106. The carriage assembly 110 also generallysupports the medical instrument 102 for positioning and insertionthereof.

Referring still to FIG. 1B, the frame 104 will now be described ingreater detail. The frame 104 includes a baseplate 112 and a drivesupport plate 114 connected thereto to at least partially form a housingof the medical insertion device 100. Other sidewalls or plates (notshown) may also form part of the frame 104. The frame 104 also includesa drive plate strengthening bracket 116 for strengthening of theconnection between the baseplate 112 and the drive support plate 114.Other strengthening brackets (not shown) may also be used. The baseplate112 may also include alignment fiducials 113 or other alignment markersfor correlating the physical world with an imaging system (not shownhere). An additional alignment fiducial 113 a or fiducials may be placedon the elongate mounting arm 120 (e.g. device holder 126), or on themedical instrument 102 itself (not shown), for correlating orregistration purposes. In some example embodiments, the alignmentfiducials can include MR molecular tagging. In some example embodiments,the frame 104 encloses almost an entirety of the medical insertiondevice 100, save for the frame 104 further including or defining anopening at the front for passage of the medical instrument 102 therethrough. In yet further embodiments, the frame 104 is integrated into orforms part of a same frame (not shown here) of the particular imagingsystem (not shown here). The frame 104 can be panel shaped to fit withinrestricted environments having a limited height.

Referring still to FIG. 1B, the carriage assembly 110 includes anelongate mounting arm 120, wherein the mounting arm 120 includes aninsertion track 122 which runs along a length of the mounting arm 120.An insertion carriage 124 includes a mechanism such as a pneumatic orpiezoelectric motor which can move or step the carriage 124 along theinsertion track 122. The insertion carriage 124 is therefore slideablymounted to the insertion track 122. A device holder 126 is connected tothe carriage 124. The device holder 126 is generally tubular shaped andacts as an interface to receive or interface with the medical instrument102. As shown in FIG. 1B, the device holder 126 includes a sheath toreceive a corresponding tubular-shaped main body 128 of the medicalinstrument 102. Thus, movement of the insertion carriage 124 along theinsertion track 122 causes the medical instrument 102 to move in aninsertion direction 127. In the example shown, the mounting arm 120 alsodefines the insertion direction 127. In some example embodiments, themounting arm 120 and/or the device holder 126 includes a force sensor(s)to detect the tissue being penetrated, and for prevention of accidentalexcursion into the incorrect tissue (e.g. chest wall).

Referring still to FIG. 1B, the medical instrument 102 typicallyincludes the main body 128 and an elongate member 130 such as a needlewhich extends from the main body 128. In example embodiments, theelongate member 130 is formed from MR compatible materials such ascarbon fibre, ceramic, or tritanium. One example of the medicalinstrument 102 is a biopsy tool 103, such as a vacuum assisted biopsy(VAB) device available from ATEC (TM), as would be understood in theart. The elongate member 130 can also include an ablative tool such asRadio Frequency (RF) ablation, focused ultrasound, cryotherapy, laserand other ablative technologies that are administered within thecancerous region causing cell destruction with minimal damage tosurrounding tissues. In some example embodiments, the medical instrument102 may also include a detector such as a probe, ultrasound probe, orfiber optic probe. The detector can also include an MRI coil to providehigher resolution in situ imaging. In yet further example embodiments,the medical instrument 102 may be integrated with the device holder 126to result in a dedicated-purpose insertion device. In yet furtherexample embodiments, the medical instrument 102 can include an endeffector or end effectors.

Reference is now made to FIG. 2, which shows the medical instrument 102in a retraction configuration or orientation. As shown, the insertioncarriage 124 is located at a proximal end of the insertion track 122,which therefore has retracted the medical instrument 102 backwards alongthe insertion direction 127 (with respect to FIG. 1A). From thisposition, the insertion carriage 124 can move along the insertion track122 to the distal end of the insertion track 122, resulting in themedical instrument 102 moving in the insertion direction 127 to aninsertion configuration or orientation as shown in FIG. 1A.

In example embodiments, referring again to FIG. 1B, the carriageassembly 110 generally includes one or more carriages which includingpivot connections and/or slideable connections for effecting positioningof the mounting arm 120, and therefore positioning of the medicalinstrument 102. Once at the desired position, the next step is typicallyan insertion step through the skin which includes movement of theinsertion carriage 124 along the insertion track 122 in the insertiondirection 127.

In the example shown in FIG. 1B, the carriage assembly 110 includes afirst carriage coupling 131 and a second carriage coupling 132. Thefirst carriage coupling 131 includes a first carriage 134 and a secondcarriage 136. The second carriage coupling 132 includes a third carriage138 and a fourth carriage 140. As shown, the first carriage 134 viafirst sway arm 135 is connected to a distal end of the mounting arm 120using a ball-and-socket pivot connection, which is defined by a ball 142of the mounting arm 120 and a corresponding socket 144 of the first swayarm 135. Such a pivot connection therefore permits pitch or yaw of themounting arm 120 in operation. The first carriage 134 also itselfincludes a pivoting (e.g. hinged) connection 148 with the first sway arm135 at the linear slide assembly 106. The first sway arm 135 is alsohingedly connected to a first coupling arm 146. The first coupling arm146 is hingedly connected to the second carriage 136.

The third carriage 138 is connected to a proximal end of the mountingarm 120 via a second sway arm 139, using a pivoting connection 150 suchas a first hinge coupled with a second hinge, as shown. The second swayarm 139 is hingedly connected to a second coupling arm 152. The secondcoupling arm 152 is hingedly connected to the fourth carriage 140. Thethird carriage 138 also includes a pivoting (e.g. hinged) connection 154to the second sway arm 139 at the linear slide assembly 106.

Referring still to FIG. 1B, the linear slide assembly 106 provides asupport for the carriage assembly 110, and includes a first track system160 and a second track system 162 having mechanisms for individually orcollectively controlling of the positioning of the carriages 134, 136,138, 140. As shown, the first track system 160 supports the firstcarriage coupling 131 and the second track system 162 supports thesecond carriage coupling 132. The first and second track systems 160,162 include straightly moveable or slideable connections with therespective carriages 134, 136, 138, 140 for facilitating lineartranslation of the carriages 134, 136, 138, 140.

Referring to the first track system 160, this includes four rails 164a-d, which correspond respectively to channels 166 a-d defined by thefirst carriage 134 and channels 168 a-d defined by the second carriage136, as shown in FIG. 1B. In the example embodiment shown, first andfourth rails 164 a and 164 d are smooth rails which act as guide railsfor sliding of the first carriage 134 and the second carriage 136. Thus,channels 166 a, 166 d, 168 a, and 168 d may also have smooth innersurfaces. Second rail 164 b includes a lengthwise screw threaddefinition which engages corresponding anti-backlash nut (not shown)within channel 166 b of the first carriage 134. Channel 168 b of secondcarriage 136 has a smooth inner surface. Thus, rotation of second rail164 b results in horizontal translation of first carriage 134 while notaffecting the second carriage 136. Similarly, third rail 164 c includesa lengthwise screw thread definition which engages correspondinganti-backlash nut (not shown) within channel 168 c of the secondcarriage 136. Channel 166 c of first carriage 134 has a smooth innersurface. Thus, rotation of the third rail 164 c results in horizontaltranslation of the second carriage 136 along the first rail system 160while not affecting the first carriage 134.

In example embodiments, a similar configuration may be used for thesecond track system 162, which includes four rails 170 a-d, whichcorrespond respectively to channels 172 a-d defined by the thirdcarriage 138 and channels 174 a-d defined by the fourth carriage 176, asshown in FIG. 1B. In the example embodiment shown, first and fourthrails 170 a and 170 d are smooth rails which act as guide rails forsliding of the third carriage 138 and the second carriage 140. Thus,channels 172 a, 172 d, 174 a, and 174 d may also have smooth innersurfaces. Second rail 170 includes a lengthwise screw thread definitionwhich engages corresponding screw threads of channel 172 b of the thirdcarriage 138. Channel 174 b of fourth carriage 140 has a smooth innersurface. Thus, rotation of second rail 170 b results in horizontaltranslation of third carriage 138 while not affecting the fourthcarriage 140. Similarly, third rail 170 c includes a lengthwise screwthread definition which engages corresponding screw threads of channel174 c of the fourth carriage 140. Channel 172 c of third carriage 138has a smooth inner surface. Thus, rotation of the third rail 170 cresults in horizontal translation of the fourth carriage 140 along thesecond rail system 162 while not affecting the third carriage 138.

Referring still to FIG. 1B, reference is now made to the rotary driveassembly 108, which acts to drive the various tracks of the linear slideassembly 106, for driving of the various carriages 134, 136, 138, 140 ofthe carriage assembly 110. In the example embodiment shown, the rotarydrive assembly 108 includes four rotary drive units 180 a-d (each orindividually referred to as 180) each corresponding to a respectiverotary drive belt 182 a-d. As shown, rotary drive unit 180 a is coupledto rail 164 b, rotary drive unit 180 b is coupled to rail 164 c, rotarydrive unit 180 c is coupled to rail 170 b, and rotary drive unit 180 dis coupled to rail 170 c.

Reference is now made to FIGS. 3A and 3B, which show a rotary drive unit180 in greater detail, in accordance with an example embodiment. Asshown in FIG. 3B, the drive unit 180 includes, in sequential adjoiningorder, a pulley 200 for engaging the drive belt 182 a-d, a retainingring 202, a ceramic bearing 204, a front motor plate 206, a ceramic ring208, a drive shaft 210, a second ceramic ring 212, a second ceramicbearing 214, one or more spacer plates 216 (two shown), a back motorplate 218, and a controller such as a microcontroller or encoder 220.Four motors such as ultrasonic motors 222 can be used to drive the driveshaft 210, which are controllable by the encoder 220. An examplesuitable ultrasonic motor 222 is a HR2 motor by Nanomotion Ltd., aswould be understood in the art. In other example embodiments,vacuum-actuated drivers or hydraulic drivers may be used.

Referring still to FIG. 1B, various modes of operation of the medicalinsertion device 100 can be effected to position the medical instrument102 by slideably moving at least one of the carriages 134, 136, 138,140. For example, for each carriage coupling 131, 132 the individualcarriages may be moved so that relative motion (left or right) betweentwo carriages will raise one end of the mounting arm 120 up or down,either linearly or in a slightly curved trajectory. The slightly curvedtrajectory also results in axial rotation of the medical instrument 102.Translation of the two carriages couplings 131, 132 in unison results ina linear translation left and right. A differential motion left andright between the first carriage coupling 131 and the second carriagecoupling 132 results in a horizontal angular motion (yaw), while adifferential vertical motion between the first carriage coupling 131 andthe second carriage coupling 132 results in a vertical angle (pitch).Raising or lowering the first carriage coupling 131 and the secondcarriage coupling 132 in unison results in a combined vertical motion.

Reference is thus made to FIGS. 4A and 4B, which show the medicalinsertion device 100 in a pitch up configuration. As shown, to effectthe pitch up configuration, the first carriage 134 and the secondcarriage 136 are slideably moved relatively towards each other. In someembodiments, only one of the first carriage 134 and the second carriage136 is moved towards the other, resulting in a slightly curved pitch uptrajectory. This slightly curved trajectory also results in axialrotation of the medical instrument 102. In another example embodiment(not shown), a pitch down may be effected by having the first carriage134 and the second carriage 136 slideably moved relatively away fromeach other.

Reference is also made to FIGS. 5A and 5B, which show the medicalinsertion device 100 in a straight insertion configuration. As shown, toeffect the straight insertion configuration, at least one of thecarriages 134, 136, 138, 140 are slideably moved to cause the medicalinstrument 102 to be horizontally oriented, which would be rectilinearto the insertion target.

Reference is now made to FIGS. 6A and 6B, which show the medicalinsertion device 100 in a translated configuration. As shown, all of thecarriages 134, 136, 138, 140 are slideably moved at the samedisplacement in a direction, for example left (as shown) or right.

Reference is now made to FIGS. 7A, 7B and 7C, which show the medicalinsertion device 100 in a yaw configuration. As best shown in FIG. 7C,the carriages 138, 140 of the second carriage coupling 132 can becollectively moved leftwardly relative to the first carriage coupling131 to result in the medical instrument 102 being angled in a yaw rightdirection. Similarly, the carriages 138, 140 of the second carriagecoupling 132 can be collectively moved rightwardly relative to the firstcarriage coupling 131 to result in the medical instrument 102 beingangled in a yaw left direction (not shown).

Referring again to FIG. 1B, it can be appreciated that the medicalinsertion device 100 can effect various insertion angles of the medicalinstrument 102 which vary from a straight insertion. It may beappreciated that the various insertion angles may provide flexibility inperforming the particular procedure. Further, it may be appreciated thatthe medical insertion device 100 may provide a stable insertion anglefor the subsequent insertion step. In addition, the medical instrument102 may for example be able to reach additional target regions such asthose near the edges of the frame 104 (e.g. at regions beyond the linearslide assembly 106 closer to the baseplate 112).

It may also be appreciated that a difficulty with some existingconventional systems is that conventional articulated or snake-likerobotic arms may not be able to provide the required stability orcontrol for performing such a procedure within an imaging system, andespecially for the final subcutaneous insertion step of the needlethrough the skin and tissue.

Referring again to FIG. 1B, in another mode of operation, it can beappreciated that the device holder 126 can be reversed, in that the body128 of the medical instrument 102 can be inserted into the other opening184 of the device holder 126. For example, the configuration shown inFIG. 1B may be used for superior (from the head) insertion at the rightbreast in a “right side” configuration. The entire medical instrument102 (e.g. the frame 104) can then be reversed with the body 128 of themedical instrument 102 inserted into the other opening 184 of the deviceholder 126 for superior insertion at the left breast in a “left side”configuration. Of course, in the “left side” configuration thereferences herein to proximal and distal would be reversed. It may beappreciated that such a reversible configuration could provide operationof the device 100 in a limited space environment such as within an MRI(not shown here).

Suitable materials for the various described assemblies and subsystemsof the device 100 include magnetic resonance (MR) compatible materials,ceramics, thermo-plastics and thermo-sets. Additional example materialsmay also include carbon fiber, ceramic, composites, nanoparticlecomposites, aluminium, titanium, and stainless steel. Examples of MRcompatible motors include piezoelectric motors, pneumatic,vacuum-actuated drivers or hydraulic drivers.

Variations may be made to the device 100 in example embodiments. Forexample, in some example embodiment, an insertion mechanism may be usedto move the entire linear slide assembly 106 in the insertion direction127 to provide the insertion step (rather than from the insertion track122). In some additional embodiments, some medical instruments 102 mayinclude their own insertion or injection mechanism, which may beautomated or manually controlled. For example, in some exampleembodiments, only a part of the medical instrument 102 such as theelongate member 130 (e.g. a needle) is independently controllable by amechanism for insertion.

Reference is now made to FIGS. 8A and 8B, which shows a dispenser system300 in accordance with an example embodiment. The dispenser system 300can for example be used with an imaging system (not shown here) todispense one or more medical instruments 302 a-h (each or individuallyreferred to as 302) to the medical insertion device 100 (FIG. 1A). Asshown, the dispenser system 300 includes a dispenser frame 304 which canbe adjoined or attached to the particular imaging system. The dispenserframe 304 includes or defines a plurality of instrument holders 306 a-h(each or individually referred to as 306) for respectively holding themedical instruments 302 a-h. The instrument holders 306 a-h can alsoreleasably secure the medical instruments 302 a-h using a retainingmechanism (not shown).

As shown in FIG. 8A, the dispenser system 300 can also include areceiver 308 which can receive the desired medical instrument 302 fordispensing, in this example medical instrument 302 a. The receiver 308can include a mechanism or a vacuum or air pump (not shown) forobtaining the medical instrument 302 a from the particular instrumentholder 306 a. The receiver 308 can also include appropriatesterilization mechanisms (not shown) such as an alcohol spray, etc.

As shown in FIG. 8A, each instrument holder 306 is arranged on thedispenser frame 304 around a centre of rotation 310 of the dispenserframe 304. The dispenser frame 304 can further include a rotatingmechanism (not shown) for rotating of the dispenser frame 304 around thecentre of rotation 310. Thus, for example, rotation of the dispenserframe 304 can be effected until the desired medical instrument 302 isaligned with the receiver 308 for dispensing.

In some example embodiments, each of the medical instruments 302 a-h canhave a universal body which can each interchangeably be used with themedical insertion device 100. In the example embodiments shown, themedical instruments 302 a-h can each have a similar elongate cylindricalbody for interfacing with a corresponding shape of the device holder 126(FIG. 1A). It can be appreciated that the dispenser system 300 thereforegenerally acts as a holster for the medical instruments 302 a-h.

Reference is now made to FIGS. 8C and 8D, which show a dispenserassembly 320 in accordance with another example embodiment. FIG. 8Cshows a lateral mode of dispensing while FIG. 8D shows an upper mode ofdispensing. In the lateral mode (FIG. 8C) the instrument holders 306 aredirected laterally (sideways) for accessing of the medical instruments302. In the upper mode (FIG. 8D) the instrument holders 306 are directedupwardly for accessing of the medical instruments 302. As shown, thedispenser system 300 is mounted onto a stand 322. The stand 322 includesa plurality of wheels 324 (e.g. five), which are lockable once wheeledto the desired position. The stand 322 also includes a swivel mechanism324, which can swivel and lock the dispenser system 300 between thelateral mode (FIG. 8C) and the upper mode (FIG. 8D).

Reference is now made to FIGS. 9A to 9C, which show a robotic surgicalsystem 400 including a magnetic resonance imaging (MRI) system 402 inaccordance with an example embodiment. As shown, a breast imagingassembly 404 can be used with a patient support table 406. The patientlies prone on top of the assembly 404 with the sternum resting on acentral support beam (not shown). The patient's head is supported byhead support 408. The patient's shoulders are supported by shouldersupports 410. The patient's breasts extend down into the breast imagingassembly 404. As shown, the patient may be put into the magnet bore holeof the MRI system 402 head first. Alternatively, the patient may beinserted feet first into the MRI system 402.

The breasts are compressed by compression plates 412, wherein thecompression plates 412 may compress the breast either in a head/feetdirection or a lateral direction. When compressing, the compressionplates 412 act as a breast stabilization mechanism. In other exampleembodiments, the compression plates 412 can include a plastic plate witha grid of finely-spaced needle guide holes. In the example embodimentshown in FIG. 9A, the compression plates 412 are oriented along thehead/feet direction. The compression plates 412 can further include aplastic plate with large rectangular access windows, which isadvantageous when used for positioning of the medical instruments 302.In yet further embodiments, a non-compressive stabilization device maybe used.

As best shown in FIG. 9C, the medical insertion device 100 can bedimensioned to be positioned in the limited space located between thehead support 408 and the patient support table 406, typically having arestricted height as shown.

In an alternate embodiment, the compression plates 412 are orientedalong the lateral direction and the medical insertion device 100 ispositioned laterally for procedures to be performed outside of themagnet bore hole of the MRI system 402.

The position of the alignment fiducials 113 (FIG. 1B) relative to thetumor is measured or located on the MR images. The appropriate positionand/or angle of the medical instrument 102 can then be determined, andthe medical instrument 102 is moved to that position and/or angle usingthe medical insertion device 100. In another example embodiment, aproper needle entry hole can be determined by determining which hole inthe compression plate 412 is closest to the desired entry point, aswould be understood in the art.

It can be appreciated that the closed geometry RF coils may be used witha plurality of windings, which can interfere with a lateral or medialbiopsy approach direction in some existing conventional systems.

Generally, the tip of the biopsy device (or ablative device) may be seenin the image and can be accurately steered towards a suspected lesionlocation as imaging continues. This will allow adjustments to thetrajectory of the biopsy device which are necessary if the lesionlocation moves for any reason. In the case of ablative therapy, therobotic manipulation system allows the tool to be repositioned asnecessary, in-situ, in order to achieve the goals of the intervention.As mentioned, alignment fiducials (not shown) may also be placed ontothe medical instrument 102 to assist in registration.

Referring to FIG. 9A, in some example embodiments, the dispenser system300 can be mounted onto a front of the frame of the MRI system 402. Insuch embodiments, the medical insertion device 100 can be swung out orotherwise controlled to access the dispenser system 300. In anotherexample embodiment, also shown in FIG. 9A, the dispenser assembly 320can be rolled and locked into position adjacent to the front of the MRIsystem 402. In other example embodiments, the dispenser system 300 canbe integrated within or attached to the patient support table 406 fordispensing of the various medical instruments 302. In such embodiments,the medical insertion device 100 may, for example, pitch down into thetable 406 to obtain or replace the medical instrument 102.

As shown in FIG. 9B, in some example embodiments, the dispenser system300 can be mounted onto a rear side of the frame of the MRI system 402,for example in the upper mode of dispensing. In another exampleembodiment, also shown in FIG. 9B, the dispenser assembly 320 can berolled and locked into position adjacent to the rear side of the MRIsystem 402.

Reference is now made to FIGS. 10A to 10C, which show a robotic surgicalsystem 500 including a mammography system 502 in accordance with anexample embodiment. The mammography system 502 can, for example, includean X-Ray based system, an MBI system, or a positron emission mammography(PEM) based system. In PEM/MBI, prior to imaging, an agent is injectedinto the patient which assists in detection of the lesion. Compressionplates 504 a, 504 b are used to provide stability and immobilization ofthe breasts. The compression plates 504 a, 504 b can also include PEMdetectors mounted thereon.

As shown in FIG. 10C, there is a limited space in the region transverseto the patient between the compression plates 504 a, 504 b. In exampleembodiments, the medical insertion device 100 is dimensioned to fit inthis transverse region between the compression plates 504 a, 504 b.Referring briefly again to FIG. 1A, a height of the drive support plate114 of the frame 104 can be dimensioned to fit within the transversespace between the compression plates 504 a, 504 b. In another embodiment(not shown), the medical insertion device 100 is mounted onto the lowercompression plate 504 b within this transverse region.

As shown, a robotic arm 506 has one end mounted to the mammographysystem 502 and the other end has the medical insertion device 100mounted thereon. The robotic arm 506 can, for example, place the medicalinsertion device 100 between the compression plates 504 a, 504 b at theappropriate time of the procedure. In other embodiments (not shown), therobotic arm 506 can place the medical insertion device 100 for superiorinsertion (e.g., from the head) with the compression plates 504 a, 504 bmounted transversely (for transverse compression) or otherwise suitablymodified.

In some example embodiments, as shown in FIG. 10B, the dispenser system300 can be mounted within the frame of the mammography system 502. Insuch embodiments, the medical insertion device 100 can controlled ormaneuvered to access the dispenser system 300 using the robotic arm 506.In some example embodiments, the dispenser system 300 does not rotatebut rather the robotic arm 506 is used to retrieve the medicalinstrument 302 from the appropriate instrument holder 306.

As shown in FIG. 10C, grid marks 510 may be shown in the virtual imageto guide the medical insertion device 100 to the target site.

After the core biopsy is performed, the medical insertion device 100provides an opportunity for other minimally invasive diagnosticprocedures and treatments. Examples include: (1) gamma detectors; (2)energized tunneling tips to reduce tunneling forces; (3) inserts to aidin reconstruction of removed tissue (e.g., one or two sided shaverinserts); (4) spectroscopy imaging devices; (5) general tissuecharacterization sensors {e.g., (a) mammography; (b) ultrasound,sonography, contrast agents, power Doppler; (c) PET and FDG([Flourine-18]-2-deoxy-2-fluoro-glucose); (d) MRI or NMR, breast coil;(e) mechanical impedance or elastic modulus; (f) electrical impedance;(g) optical spectroscopy, raman spectroscopy, phase, polarization,wavelength/frequency, reflectance; (h) laser-induced fluorescence orauto-fluorescence; (i) radiation emission/detection, radioactive seedimplantation; (j) flow cytometry; (k) genomics, PCR (polymerase chainreaction)-brca1, brca2; (I) proteomics, protein pathway}; (6) tissuemarker sensing device; (7) inserts or devices for MRI enhancement; (8)bishops on-a-stick; (9) endoscope; (10) diagnostic pharmaceutical agentsdelivery devices; (11) therapeutic anti-cancer pharmaceutical agentsdelivery devices; (12) radiation therapy delivery devices, radiationseeds; (13) anti-seeding agents for therapeutic biopsies to block therelease of growth factors and/or cytokines (e.g., chlorpheniramine (CPA)is a protein that has been found to reduce proliferation of seededcancer sells by 75% in cell cultures.); (14) fluorescent taggedantibodies, and a couple fiber optics to stimulate fluorescence from alaser source and to detect fluorescence signals for detecting remainingcancer cells; (15) positive pressure source to supply fluid to thecavity to aid with ultrasound visualization or to inflate the cavity tounder the shape or to reduce bleeding; (16) biological tagging deliverydevices (e.g., (a) functional imaging of cellular proliferation,neovacularity, mitochondrial density, glucose metabolism; (b)immunohistochemistry of estrogen receptor, her2neu; (c) genomics, PCR(polymerase chain reaction)-brca1, brca2; (d) proteomics, proteinpathway); (17) marking clips; (18) mammotome; and (19) obturator trocar;(20) ablative therapies (cryo, RF, laser, etc.).

Reference is now made to FIG. 11, which shows a block diagram of arobotic surgical system 10 to which example embodiments may be applied.The system 10 includes a surgical robot 12 for use in a surgicalenvironment. The surgical robot 12 is in communication with a controlstation 16 either over a communications network 18 (as shown), or via adirect connection. Generally, the surgical robot 12 includes one or morerobotic instrument(s) 24 which can be operational in a limited sizeoperating environment defined by an imaging system such as magneticresonance imaging (MRI). At least one of the robotic surgicalinstruments 24 may include the medical insertion device 100 as shown inFIG. 1A.

Referring still to FIG. 11, the surgical robot 12 includes a controller20 for controlling operation of the surgical robot 12, a communicationsmodule or subsystem 22 for communicating with the control station 16over the network 18, and robotic surgical instruments 24 which arecontrollable by the control station 16 over the network 18. In anexample embodiment, the robotic surgical instruments may be hapticallycontrollable which can include force-feedback or touch-feedback control.The controller 20 can include one or more microprocessors or processorsthat are coupled to a storage 21 (e.g. computer readable storage medium)that includes persistent and/or transient memory. The storage 21 storesinformation and software enabling the microprocessor(s) of controller 20to control the subsystems and implement the functionality describedherein. The surgical robot 12 includes a detector subsystem 28 fordetermining spatial information relating to a surgical environment ofthe surgical robot 12 (including a subject patient) and sending/relayingsaid information to the control station 16 over the network 18. Asshown, in some example embodiments the detector 28 may include a camera30 (for capturing video and/or audio information), an x-ray system 32,an ultrasound system 34, an MRI 36, or others such as Positron EmissionTomography (PET), Positron Emission Mammography (PEM), CT lasermammography, or a GE (TM) molecular biological imager. In some exampleembodiments, the controller 20 is configured to operate or provide alocal control loop between at least one of the subsystems and therobotic surgical instruments 24.

The control station 16 includes a controller 40 for controllingoperation of the control station 16 and a communications subsystem 42for communicating with the surgical robot 12 over the network 18. Thecontroller 40 is coupled to a storage 41. A control console 44 providesan interface for interaction with a user, for example a surgeon. Thecontrol console 44 includes a display 46 (or multiple displays), and auser input 48. In some embodiments, the user input 48 may furtherinclude haptic controllers (not shown) for allowing the user tohaptically control the robotic surgical instruments 24 of the surgicalrobot 12, for example with force-feedback or touch control. Althoughonly one control station 16 is shown, in other embodiments two or morecontrol stations may be used, each configured for controlling at leastpart of the surgical robot 12. An example interface is shown in FIG. 12,which in example embodiments includes a graphical user interface (GUI)for interfacing with the user.

Generally, the system 10 can be used to perform a procedure by breakingdown a procedure into a series of interconnected sub-tasks. Some of thesub-tasks are performed automatically by the surgical robot 12 tocontrol the robotic instruments 24 and the subsystems to perform theparticular sub-task. Some of the other sub-tasks are “semi-automated”,meaning having some control from the control station 16 as well as somelocal control from the controller 20.

Each defined sub-task may for example be stored in a storage 21accessible by the controller 20, the storage 21 including a library. Thelibrary includes a sequence of sub-tasks (both automated and“semi-automated”). Specifically, some of the sub-tasks have instructionsto automatically control the robotic instruments 24 and the subsystemsto perform the sub-task. During automated control, the controller 20 mayautomatically perform the surgical functions by providing the localcontrol loop with the subsystems. Some of the other sub-tasks may be“semi-automated”, meaning having some control from the control station16 as well as some local automation (with the controller 20 providinglocal control loops as described herein). During semi-automated control,the control station 16 and the subsystems may be in a master-slaverelationship. In example embodiments, such semi-automated control may beconfigured in an external control loop as between the subsystems and therobotic instruments 24, which are facilitated by the control station 16.

The sub-task may be selectively retrieved from the library and combinedinto a defined sequence or sequences to perform the surgical procedure.The flow from one sub-task to another is stored in the library. Eachsub-task may use imagery and other parameters to verify sub-taskcompletion. In some example embodiments, each of the sub-tasks in aparticular entire procedure may be automatically performed by thesurgical robot 12.

For example, for a breast biopsy a first sub-task may be thesemi-automated positioning of the medical insertion tool 100 by thesurgeon in front of the desired insertion region, while the secondsub-task may be the automated insertion of the biopsy needlesubcutaneously into the target site.

Referring again to FIG. 11, the robotic surgical instruments 24 mayinclude any number or combination of controllable mechanisms. Therobotic surgical instruments 24 include end effectors such as grippers,cutters, manipulators, forceps, bi-polar cutters, ultrasonic grippers &probes, cauterizing tools, suturing devices, etc. The robotic surgicalinstruments 24 generally include small lightweight actuators andcomponents. In some example embodiments, the robotic surgicalinstruments 24 include pneumatic and/or hydraulic actuators. Suchactuators may further assist in providing motion stability, as furtherdescribed below. In some example embodiments, various lightweightradiolucent materials for robotic arms as well as the range jointtorques, forces, frequency response, ROM, weight and size of differentactuators to achieve the maximum function in the surgical robot 12. Inanother example embodiment, the robotic surgical instrument 24 may beconfigured to include a therapeutic tool utilizing the administration ofhigh intensity focused ultrasound (HIFU) to control haemorrhage andtreat solid tumours. Both the HIFU and the ultrasound 34 (for detectingthe surgical environment) may be implemented within the same roboticsurgical instrument 24.

Referring still to FIG. 11, the detector subsystem 28 will now bedescribed in greater detail. The incorporation of intra-operative imageguidance into surgical robotics provides an additional capability torefine the precision of a surgical procedure. Pre-operative diagnosticimagery may be utilized to plan surgical procedures with the assumptionthat these diagnostic images will represent tissue morphology at thetime of surgery. Along with this pre-operative planning, intra-operativeimagery may also be used to modify or refine a present surgicalprocedure or administer minimally invasive treatment such as HIFUultrasound therapy used to control bleeding.

One aspect of such image-guided surgery in accordance with exampleembodiments is registering multiple images to each other and to thepatient, tracking instruments intra-operatively and subsequentlytranslating this imagery for real time use in the robot space. Theincorporation of medical imagery into surgical planning for the system10 facilitates the identification of a defined work envelope for singleor multiple robotic arms. Intra-operative tracking of the position ofthe robotic surgical instruments 24 within the defined work envelope canbe utilized to develop local control loop systems between the detector28 and the robotic surgical instruments 24 to define keep-out and workwithin zones for surgical tasks. This data is incorporated into knownalgorithms developed for collision avoidance of the multiple roboticarms and optimization of the position of instrumentation for completionof the surgical task.

Different technologies that incorporate a physical marker, such as MR,X-Ray, IR (Infrared) markers or RF (Radiofrequency) devices, or chemicalmarkers, may be used for image registration of specific anatomicallandmarks for both the intra-operative tracking of the surgical robot 12in relation to the patient as well as tracking the surgicalinstrumentation. Image-based registration is less sensitive tocalibration and tracking errors as it provides a direct transformationbetween the image space and the instrument space. The information fromanatomical landmarks can be registered with the diagnostic imagery usedto plan the surgical procedure and subsequently translated into therobotic space for completion of an image guided surgical procedure. Thistranslation is performed using a registration procedure between therobot and the imaging device. The incorporation of real-timeintra-operative tracking of anatomical landmarks provides a mechanism ofincorporating compensatory motion of the robotic arm to accommodatepatient movement thereby enhancing the precision of the robotic task.

In another example embodiment, the detector subsystem 28 includes theincorporation of image guidance into the robotic surgery, includingpredetermined marker shapes and positions that provide optimal accuracyfor fiducial marker monitoring and tracking of anatomical landmarks,instrument position and the position of the robotic arms under theconstraints imposed by the imaging device and the limited volumeavailable in the surgical work envelope.

Imagery can also be incorporated as one of many parameters used toprovide local control loop feedback in performing autonomous robotictasks. In some example embodiments, the control station 16 and thesurgical robot 12 operate in a master slave relationship. Suchembodiments may incorporate semi-autonomous surgical robotics whereinthe surgical robot 12 may autonomously perform some specified surgicaltasks that are part of a sequence of a larger task comprising thesurgical procedure, for example using a locally controlled loopimplemented by the controller 20. This may for example enables thesurgeon to selectively perform techniques best undertaken with a masterslave relationship while using automated robotics to perform specifictasks that require the enhanced precision of a surgical robot. Forexample, such tasks may include the precision placement of brachytherapyfor cancer treatment or the precision drilling and intra-operativepositioning of hardware in orthopaedic surgery.

In another aspect the control station 16 displays diagnostic images,uploaded from a diagnostic workstation (such as CT, MRI, or the like),such that a clinician may select start (insertion point) and end(lesion) location points. A 3D representation of the 2D image slice datawith controllable view angle enables the clinician to plan an optimalpath avoiding blood vessels and other tissue structures. The avoidanceof hematoma can be important with regard to post biopsy image qualityfor target confirmation.

The control station 16 calculates the linear and angular motionsnecessary to move the surgical robotic manipulator over the plannedtrajectory and send appropriate commands to plurality of motors to movethe medical instrument.

Referring still to FIG. 11, the communications network 18 may furtherinclude a direct wireless connection, a satellite connection, a widearea network such as the Internet, a wireless wide area packet datanetwork, a voice and data network, a public switched telephone network,a wireless local area network (WLAN), or other networks or combinationsof the forgoing.

In one aspect the surgical robot 12 can move the medical instrument 100while diagnostic images are being acquired. This can reduce thetargeting confirmation time can be critical in light of contrastenhancement degradation issues. In addition, targeting errors as aresult of lesion motion due to the force of the advancing needle, forexample, can also be adjusted with the patient remaining within themagnet bore hole. The automated steering uses targeting software as wellas force sensors to prevent accidental excursion into the wrong tissue.The software allows the medical practitioner to plan the full trajectoryof the needle or ablation instrument from the skin surface down to thelesion and to steer the medical instrument 100 using real time MR.Again, MR fiducials as well as of MR molecular tagging may also be usedto improve targeting accuracy.

In yet another aspect a remote control station 16 can enable control ofthe robotic instruments 24 from a distance such that an expert in thebreast biopsy and ablation procedures will direct the procedure from adistance. The remote control station 16 can connect to one or more localworkstations such that one physician may perform procedures at aplurality of remote sites (the master controller is at the remote site).Alternatively, the local workstation may control the procedure and aremote station will monitor the procedure for teaching purposes, forexample. Examples of various systems which can use local and remoteworkstations collaboratively are described in the PCT Patent ApplicationNo. WO 2007/121,572, the contents of which are herein incorporated byreference.

In some example embodiments, rather than the breast biopsy or ablativeprocedures described herein, additional procedures can be performedusing several imaging modalities such as MRI, CT, PET, PEM, BSGI, X-ray,or sonography, or other modalities where there is an advantage toaccurately target a pathology for biopsy or ablation. It would also beappreciated that in some example embodiments other areas of the body canbe targeted other than the breast. Such applications include liver,axilla (sentinel node biopsy), lung, kidney, prostate, uterus, andneurological.

The various example embodiments described as systems would similarlyapply to methods, and vice-versa.
